Question

我想在我的Windows应用商店项目中使用TagLib。 TagLib作为参考导入，带有dll（taglib-sharp.dll）我可以访问我的音乐文件夹中的任何文件，因为它已在功能中进行了检查。但是，当我打电话时

TagLib.File file = TagLib.File.Create(soundFilePath, TagLib.ReadStyle.None);

它会抛出以下错误：

System.UnauthorizedAccessException was unhandled by user code
HResult=-2147024891
Message=Access to the path 'C:\Users\Gabor\Music\_FIFA 2010 soundtracks\01. Meine Stadt - Auletta.mp3' is denied.
Source=taglib-sharp
StackTrace:
   at TagLib.File.Create(IFileAbstraction abstraction, String mimetype, ReadStyle propertiesStyle)
   at TagLib.File.Create(String path, String mimetype, ReadStyle propertiesStyle)
   at TagLib.File.Create(String path, ReadStyle propertiesStyle)

Answer 1

您可以使用TagLibSharp通过创建StreamFileAbstraction并将其传递给File.Create来加载标记。这不会使用任何禁用的API。

public void ExampleCall(StorageFile storageFile)
{
    IRandomAccessStreamWithContentType f = await storageFile.OpenReadAsync();
    var file = File.Create(new StreamFileAbstraction(storageFile.Name, f.AsStream()));
}

public class StreamFileAbstraction : File.IFileAbstraction
{
    public StreamFileAbstraction(string name, Stream stream)
    {
        Name = name;
        ReadStream = stream;
        WriteStream = stream;
    }

    public void CloseStream(Stream stream)
    {
        stream.Flush();
    }

    public string Name { get; private set; }
    public Stream ReadStream { get; private set; }
    public Stream WriteStream { get; private set; }
}

不能这样做。使用了MusicProperties，然后使用lastfm api来获取所需的信息..在Win8中很难羞耻＃在普通的C＃中很容易＃

Answer 3

对于WinRT，您需要接下来：

var task = await StorageFile.GetFileFromApplicationUriAsync(uri);
var stream = await task.OpenStreamForReadAsync();
 using (var info = File.Create(new StreamFileAbstraction(Path.GetFileName(uri.LocalPath), stream, stream)))
 {
      Album = info.Tag.Album;
      Comment = info.Tag.Comment;
      // more properties
 }

您需要添加NuGet包 - TagLib #Portable
